aminophenols, 2‐[(p‐tolylamino)methyl]‐4‐(2,4,4‐trimethylpentan‐2‐yl)phenol (L'H2) and 2‐cyclohexylaminomethyl‐4‐methylphenol (L″H2), with alkyl compounds of aluminium, gallium and zinc resulted in the formation of a variety of products depending on the type of metallic centre and alkyl groups bonded to metal atoms. New trinuclear aluminium complexes (Me5Al3(L′)2 (1) and Me5Al3(L″)2 (2)), monomeric
含有氨基酚盐配体的络合物被认为是开环聚合(ROP)的非常有效的引发剂。我们对两种选定的氨基酚2 [[(对甲苯胺基甲基)]-4-(2,4,4-三甲基戊基-2-基)苯酚(L'H 2)和2-环己基氨基甲基-4的反应进行系统研究甲基苯酚(L''H 2)与铝,镓和锌的烷基化合物一起形成的产物取决于金属中心的类型和与金属原子键合的烷基。新的三核铝络合物(Me 5 Al 3(L')2(1)和Me 5 Al 3(L'')2(2)),单体铝(t Bu 2 Al(L'H)(3)和t Bu 2 Al(L''H)(5))和镓(t Bu 2 Ga(L'H)(4)和t Bu 2 Ga(L''H)(6))化合物,以及双核镓(Et 2 Ga(L''H)·Et 3 Ga(7))和锌(t BuZn(L''H)] 2(8))络合物被隔离和表征。7和8的分子和晶体结构是根据X射线衍射研究确定的。聚合试验表明,只有3个配合物(6 -
